RETHINKING THE DAIRY HERD RENEWAL POLICY ISSUE

Abstract

The objective of the study is to improve ways for calculating the optimaldairy herd replacement strategy. Research has been conducted based on data fromLLP "Olzha-Sadchikovskoe" inKostanay oblast for the period of 2018 to 2020.The greatest difficulties in solving the problem arise when optimizing the planfor renewing the existing herd with animals with higher productive potential. This isbecausecows of different productive ages have different economic value due tochanges in their milk productivity with age with a certain regularity. The widespreaduse of herd renewing policy optimization methods is limited due to the lack of datarelating to the patterns of change in the economic value of animals depending ontheir age, and some probabilistic characteristics such as cow mortality rate,infertility, etc.It also should be kept in mind that the accurate forecasting of pricedynamics for milk and feed is crucial when designing an effective dairy herdmanagement strategy. And the replacing plan seems to be different and special foreach animal.
